WALTER J. GTESE, OF POWER, MONTANA. CHARGE-CONDITION APPARATUS FOR INTERNAL-201136811011 ERGINR.

Application filed July 17, 1918. Serial No. 245,884.

To all whom it may concern:

Be it known that I, WAUIER J. Green, a citizen of the United States, and a resident of Power, in the county of Teton and State of Montana, have invented certain new and useful Improvements in a Charge-Condition Apparatus for Internal-Combustion Engines, of which the following is a specification.

This invention relates to improvements in apparatus for properly conditioning fuel charges and cylinders of internal combustion engines.

The primary object of this invention is the provision of an apparatus which may selectively supply dry filtered air; moist heated air; or filtered air and moistened heated air in combination to a carburetor or other device upon an internal combustion engine, so that the same will ultimately reach the cylinders of said engine.

A further object of this invention is the provision of apparatus of the above described character which may utilize an in ternal combustion engine radiator as a source of heated moistened air, and with which an auxiliary heating device may be used until the liquid in the radiator is of such temperature as to properly heat the moistened air forpassing through said apparatus.

Other objects and advantages of this invention will be apparent during the following detailed description.

In the accompanying drawings, forming a part of this specification, and wherein similar reference characters designate ooltresponding parts throughout the several views:

Figure 1 is a side elevation of the device showlng parts thereof in section and Figure 2 is an enlarged section through the filter.

Referring more particularly to the drawings, 1 indicates a radiator of the structure generally used with an ordinary internal combustion engine such as commonly employed in tractor construction this radiator having a pipe or hose 2 connected with the upperportion thereof which is connected by means of a coupling 3 to a second pipe or conduit 4. The conduit 4 extends in down wardly sloping manner through a heater 5, which utilizes the exhaust gases from the engine as a heating medium, which exhaust gases may pass from the engine into the heater 5 through a suitable pipe 6 and out of the heater through an exhausting pipe 7. The conduit 4 is provided with an elbow portion 8 which is connected to an ordina T coupling 9. This coupling '9 has the air dellvery pipe 10 connected to the transverse connection thereof which pipe or conduit is adapted to feed the moistened air to the mixer of an engine.

pipe or conduit 11 is connected to the coupling 9 oppositely of the connection be tween the coupling and the conduit 4. The conduit 11 has communication with the interior of the casing 12 of the filtering structure and this communication is screened by an ordinary screen 13.

The cylindrical casing 12 of the filter has an annular shoulder 14 formed therein a short distance upwardly of its lower end upon which shoulder rests a-ring 15. The ring 15 supports a screen 16. A second screen" is positioned within the housing 12 below the plurality of air inlet openings 18 formed in the side of the housing near its upper end and this screen is confined within the housing against upward move ment by an expansible retaining rin 19. Suitable filtering material such as woo indicated at 20 is placed between the screens 17 and 16 and the compactness or compression of this material may be regulated by the positioning of the screen 17 and expansion ring 19. For instance in case the suction through the filter is heavy, or high, the expansion ring may be contracted and moved upwardly within the casing 12 to permit the expansion of the filtering material 20 or if it is desired to compress the filtering material the screen 17 and expansion ring 19 may be forced downwardly toward the screen 16 and when the ring 19 springs to frictional engagement with the inner surface of the housin 12 it will maintain the screen 17 in its ad uSted position.

The bottom 21 of the cylindrical housing 12 base length 22 of pipe connected thereto which has communication through the medium of a coupling 23 with the conduit 4 to permit the passage of air from the filter, into the pipe 4 for admixture with the moisture entering the conduit 4 from the conduit 2. A butterfly valve 23 is positioned within the conduit 2 for controlling the passage of the moisture and steam therethrough while the passage of the air through the pipe 22 into the conduit 4 is controlled by a butterfly valve 24. Butterfly valves 25 and 26 are provided for controlling the passage of the air and moisture from the conduits 4 and 11 respectively into the pipe or conduit 10.

Upon the starting of the engine with which the improved device is employed, the butterfly valves 25 and 24 are opened, the valve 23 is partially opened while the valve 26 is closed, thus the suction through the pipe 10 will draw the moisture from the radiator 1 through the conduits 2"and 4 and will draw air downwardly through the housing' 12 and pipe 22 into the conduit 4, where it is mixed with the moisture, and the moistened air will, upon passing through the heater 5 be heated so that heated moistened air will be supplied to the mixer of the env gine. After the engine has been running suflicientlyto heat the cooling liquid in the radiator 1, the heater 5 may be cut oil by closing valve 4 in pipe 3, the necessary heating of the air then being supplied by the heated'moisture or steam entering the pipe or conduit 4 from the radiator 1. In case the motor is getting too much moisture the valve 26 is opened and the valves 23 and 25 are partially closed.

A drain cock 30'is positioned within the pipe or conduit 4'at the lowermost point thereof to permit the draining of condensed steam or moisture therefrom,

While the apparatus herein set forth is described as used in connection with the radiator of an internal combustion engine, it is obvious that the same may receive heated moistened air from analogous sources, such as a boiler.-

Changes in details may be made without departing from the spirit of this invention.

I claim:
